Storage charges are fees assessed when cargo, containers or other equipment remain in a warehouse, port, terminal or carrier facility beyond included or agreed time. The charge basis, free period, calendar and responsible party must be identified because similar-looking fees can arise at different locations.
How are storage charges calculated?
A common method is storage charge = chargeable units × chargeable days × daily rate, sometimes with escalating rate tiers.
Illustrative storage charge calculation
| Calculation step | Value | Arithmetic |
|---|---|---|
| Included free time | 5 days | No storage charge |
| Actual facility time | 8 days | Arrival through pickup under the stated calendar |
| Chargeable time | 3 days | 8 − 5 |
| Daily rate | $90 | Illustrative rate for one unit |
| Storage charge | $270 | 1 × 3 × $90 |
The illustrative $270 excludes taxes, handling, demurrage, detention and other charges.
What should the invoice show?
Check location, cargo or equipment identifier, arrival and release events, free-time rule, chargeable dates, unit, rate tier and currency.
Storage versus demurrage and detention
Terminology varies by provider. Demurrage often concerns container time within a terminal and detention time outside it, while storage may be a separate facility charge. Use the tariff definitions.
How can charges be prevented or disputed?
Track availability, customs release, documents, appointments and pickup. For a dispute, assemble timestamps, notices, gate records and the applicable tariff rather than relying on a general delay explanation.
